' To all whom t 'may concern in Seaming Mechanism, of which the following is a specification.l

The present invention relates generally to can heading machines and has more particularly reference to seaming mechanism.

The main object and feature of the invention resides in simple and eiicient means for producing the in-and-out movement ot a seaming tool and whereby, at the same time, the parts may be properly lubricated.

In the accompanying drawings the invention is disclosed in several concrete and pre- Vferred forms, in whichseaming head embodying the invention on the irregular line l-1 of Fig. 2. p

Figure 2 is a bottom plan view of .the parts shown in Fig. 1.

Figure 3 is a horizontal sectional view on the line 3--3 of Fig. l. z

Figure 4: is a vertical sectional view similar to Fig. 1 showing a modiied i'orm of the invention.

. Figure 5 is a detail sectional view through one of the seaming tools online 5-5 of Fig. 2.

It will be understood that in machines of this character the work may be stationary or rotating, and that whenthe work is stationary the seaming tools 4travel in an orbit around the work and also have an in-andout movement with respect thereto to perform the seeming operation, but that it the work rotates the seaming tools are relatively stationary except 'for the in-and-out move ment. It is customary to providek aseaming cam which has an effective circumferential displacement with respect to the seaming tools equal to one revolution for each cycle of the machine. When the seaming tools travel in an orbit around the stationary work they make many revolutions to each cycle, and it is'customary in cases of that character to have the seaming cam also rotate a number of revolutions to each cycle of the machine, the number of revolutions of the seaming tools and seeming cams be ing unequal so that there is an effective dis- Figure l is a vertical sectional view oi a Specification of Letters Patent.y

placement of the cam with respect to the tools of one revolution for each cycle lof the machine. f When the seaming tools are relatively stationary, except for the in-and-out movement, the seaming cam makes but one revolution to each cycle of the machine.

In the exemplication ot the invention y shown in Figs. l, 2 and 3, the work is relatively stationary and the seaming tools travel in an orbit around the work, while'in the exemplication shown `in Fig. 4t the work rotates andthe seamng tools are relatively stationary, except for their in-and-out movement.

Considering first the form of the invention shown in Figs. l, 2 `and 8, a is a stationary chuckthat clamps the work against a pedestal (not shown). o is a rotating head making many revolutions to each cycle oi" the machine to which is secured a carrying member c having bottom and 'side walls as shown.` b indicates a sea-ming cam that rof tates a number of revolutions to each cycle of the machine but here at a relatively slower speed than member o; This cam is above the bottom wall koi carrying member c and with it constitutes an oil container or reservoir to which oilv may be ted from the top of the machine by way of the duct Zi. In the bottom wall ocarrying member c are two radial slots l and in these slide rcciprocating members 7c actuated from cam o and preventing egress of .theoil trom ythe container. The means for actuating each reciprocating member 7c consist oi'a cam roll e having a bolt j passing through member 7c. On the underside of the bottom wall of carrying memberc are two pivotally supported arms cl. Each arm al has a pivot d mounted in a bearing Z2 forming part of the side and bottom walls of memberc. At one end of each arm d is a seamingtool, the first operation roller being indicated by d3 and the second operation roller by di. The other Member c is secured to member 0 by means of bolts Q.

The'upper face of the bottom wallv of member c is provided with a circumferential oil groove c and from this extends an oil duct c2 to the groove c3 on arm d that in turn connects with the bearing of the seaming roller in a suitable manner.

InFig. 4L the construction is substantially the same as in Figs. 1 to 3 except that here member c is bolted to a stationary portion of framework p and chuck @rotates l y Seaming cam b is provided with two sets of cam portions, each set consistingof an active portion 21 or 22 and an inactive portion 23 or 24, the `arrangement beingV such that one active and one inactive'portion are diametrically opposite to each other, just as seaming rollers da and (Z4 and cam rollers e `are diametrically opposite to each other. Cam b is further provided with neutral portions V25 and 26 for theA purpose ot' maintaining the seaming rollers, `for a short period, in a neutral position substantially midway of their inner and outer positions.

The can to be seamed isV inserted in the machine in any customary mannerbetween chuck a and its co-operating element (not shown) this taking place when the seaming rollers are occupying their neutral4 position,

, rollers e being in engagement with cam portions 25 and 26. f

Rotation of the cam b in the direction vindicated by the arrow shown Fig. 2 will Vnow `cause cam roller e .of first operation roll Z3 to engage with neutral portion 26 Vand then with active portion 21 of the cam,

cam .roller e of the second operation roller 034 engaging, at the same time, with neutral portion25 and-thenA `with the inactive portion 23. This will cause d3 to'move toward the work to initially curl the cover and can,

and d* to move away from the work. Continued rotation of cam` Z) will 'nowbring .roller e of seaming roller d3 intol inactive portion 24:, and roller e of seaming roller d* into active portion 22. This will cause d3 to move away from and d* to move toward the work. After d* has completed its work the rollers e will enter neutral portions 25 L and 26 and the finished can is removedand another onel substituted.

' In the foregoing 'description of the operav tion of the machine, the action whichtakes Yplace during one-halfrevolution ot cam b only hasbeen set forth. It will be apparent l slots, reciprocating members sliding in said slots, two pivotallyV supported members on said carrying member, a seaming tool on onefend of each pivotally supported member, a seeming camior actuating the reciprocating members, and two links each connected to the otherv end of one pivotally supported lmember. and to one of the -reciprocating members.

2. Sea-ming mechanism comprising an oil container having bottom and side walls conf stituting a carrying member, a pivotally supported member on the lower side of the bottom wall of the carrying member, aseaming toolfon the pivotally supported mem'- ber, a seaming cam within the oil container and constituting onev of the side walls thereof, a reciprocating member actuated by said cam and sliding in the bottom ywall of said carrying member and means connecting` the reciprocating member with the pivotally supported member.

3. Seaming mechanism comprising: a carrying member having bottom and side walls, a seaming cam forming a side wallr above the bottom wall of the carrying member and constituting with the latter an oil container, a reciprocating member actuated by said cam and sliding-in the bottom wall of said carrying member, a seemingy tool, and conmember `and the seeming tool for imparting an'in-and-out movement to said seaming tool.

Anecting means between the reciprocating a bearing in said fside wall, a member pivi otally supported `on said bearing, a seammg tool carried thereby, a4 seaming cam above the bottom wall of the carrying'member, and connectionsbetween the pivotally supported member and the seaming cam.
